Describes how to inspect, clean, and repair chaps that protect the user from chain saw injuries. The chaps, developed by the Forest Service's Missoula Technology and Development Center, use five layers of Kevlar to bind the chain saw, stopping the chain, and preventing injuries. Improperly maintained chaps do not provide as much protection as chaps that are maintained according to the instructions. Chaps should be retired (taken out of service) when someone has sewn through the five-layer Kevlar pad or when the chaps have many holes and cuts.
